Background: MIER1α is a transcriptional regulator that interacts with estrogen receptor α and inhibits estrogen-stimulated growth of breast carcinoma cells. Interestingly, analysis of MIER1α subcellular localization in breast samples revealed a stepwise shift from the nucleus to the cytoplasm during progression to invasive carcinoma. Previously, we demonstrated that MIER1α is nuclear in MCF7 cells yet it does not contain a nuclear localization signal. Instead MIER1α is targeted to the nucleus through interaction and co-transport with HDAC 1 and 2.
Results: In this study, we demonstrate that treatment of MCF7 breast carcinoma cells with either insulin or insulin-like growth factor affects the subcellular localization of MIER1α. Both factors reduce the percentage of cells with nuclear MIER1α from 81 and 89 to 41 and 56%, respectively. Treatment with 17β-estradiol, on the other hand, had no effect and MIER1α remained nuclear.
Conclusions: Our data demonstrate that insulin and IGF-1 can contribute to loss of nuclear MIER1α in the MCF7 breast carcinoma cell line.

Recent evidence indicates that endocrine resistance in estrogen receptor-positive (ER+) breast cancer is closely correlated with phenotypic characteristics of epithelial-to-mesenchymal transition (EMT). Nonetheless, identifying tumor tissues with a mesenchymal phenotype remains challenging in clinical practice. In this study, we validated the correlation between EMT status and resistance to endocrine therapy in ER+ breast cancer from a transcriptomic perspective.

Background: The Golgi apparatus is widely considered a secretory center and a hub for different signaling pathways. Abnormalities in Golgi dynamics can perturb the tumor microenvironment and influence cell migration. Therefore, unraveling the regulatory network of the Golgi and searching for pharmacological targets would facilitate the development of novel anticancer therapies.

Aim: To evaluate the efficacy and safety of radiofrequency ablation (RFA) and microwave ablation (MWA) for treating cervical lymph node metastasis (CLNM) from papillary thyroid carcinoma (PTC).
Methods: Medline, EMBASE, Web of Science, and Cochrane Library were searched for studies on the efficacy and safety of thermal ablations for treating CLNM from PTC until July 2024. Among 544 papers, 11 articles were reviewed involving 233 patients and 432 CLNM cases.
Introduction: The aim of this study was to assess the long-term impact and potential effectiveness of our specialized acellular dermal matrix (ADM) in a two-stage breast reconstruction process.
Objective: Opinions regarding the use of ADMs are currently divided. While their positive contribution to reconstructive breast surgery is evident, the results of studies vary depending on specific procedures, patient selection, and techniques employed.
